The reason you are still seeing low ring voltage is due to 
the fact that the module is not using the boostringer when 
it is being loaded. If it were, you would see

PCI: Found IRQ 14 for device 00:08.0
Freshmaker version: 71
Freshmaker passed register test
Boosting ringinger on slot 1 (89V peak)
Module 0: Installed -- AUTO FXS/DPO
Module 1: Not installed
Module 2: Not installed
Module 3: Installed -- AUTO FXO (FCC mode)
Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)
Registered tone zone 0 (United States / North America)

Notice the line in there about bossting the ringer to 89V 
peak. I am not seeing that in yours.

No clue...

Are you using the USB for anything?? If not, turn it off 
in your BIOS if you have the option and don't even let it 
load.
